London property
Victorian terraces, converted flats, mansion blocks and riverside ground. What the housing stock does to the pipework beneath it.
North London drainage: what we see across N and NW postcodes
Shared laterals, conversion density and basement kitchens. The faults follow the housing.
Commercial drainage in the City and Shoreditch: working around trading hours
Catering density, Victorian sewers and permit-controlled access. The pipe is rarely the hard part.
Drainage in mansion blocks: communal runs and who arranges what
Almost everything is communal, which changes who calls, who pays and how fast it moves.
Converted flats and shared soil stacks: whose blockage is it?
The lowest flat sees it first and is rarely the cause. What decides who pays.
Clay soil and drains in south London: why joints keep opening
Seasonal ground movement works rigid clay pipework apart. It is the defining fault south of the river.
Riverside London: high water tables and slow surface water
Tidal influence and a high water table mean there is no spare capacity in the system after rain.
Basement flats and pumped drainage in central London
Why a pump alarm usually means the discharge run is restricted, not that the pump has failed.
Drainage in Victorian terraces: what London’s housing stock does to pipes
Jointed clay, shared laterals and extensions built over the run. The pattern repeats across the capital.
East London drainage: what we see across E and EC postcodes
Low ground, warehouse conversions and dense catering, all on the same Victorian network.
